FEC(forward error correction,FEC for short) is the way to increase data reliability. In a one-way communication channel, once an error is found, its receiver will not have the right to request transmission again. FEC is a method of transmitting redundant information using data. When an error occurs in transmission, the receiver is allowed to reconstruct data.
